Hi fmardani,
I take it from your post that you have been busy concentrating on the theory side of things first before the flying. Finishing off the exams now at least leaves you free to enjoy the flying. I advocate the use of PC based flight simulation as they have improved remarkably over the years. One of the popular ones is Micrsoft Flight Sim 2000/2002. They are available in either professional or standard editions. (The former is more suited to advanced training). With a good graphics card, (16mb ram or more) a decent processor and onboard ram in the 256kb area you can polish your skills quite well. One word of warning though, as PPL training involves primarily VFR flying don't fall in the trap at this critical stage of being glued to the flying instruments! Learning to fly is initially a case of visual reference to a natural horizon, not an artificial one. Flight Simulators really come into there own when learning instrument flying techniques, of which Ex19 of the PPl syllabus is all about. Nevertheless, good fun and if used carefully a great learning aid.
Good luck!
